摘要：

This paper reports the synthesis, structure, and properties of a series of PNP pincer complexes of osmium OsH3Cl[HN((C2H4PPr2)-Pr-i)(2)] (1), OsH3[N((C2H4PPr2)-Pr-i)(2)] (2), OsH4[HN((C2H4PPr2)-Pr-i)(2)] (3), and OsH2(PMe3)[HN((C2H4PPr2)-Pr-i)(2)] (4). The tetrahydride 3 operates as an efficient catalyst at 0.1 mol% loading for the reactions of amination and dehydrogenative coupling of primary alcohols, producing secondary amines and symmetrical esters, respectively. The catalyst 3 is distinguished by outstanding stability, and it can be used in an aqueous environment at temperatures as high as 200 degrees C.
